Why wasn’t Dylann Roof charged with terrorism?

– THE INTERCEPT, JULY 22 2015, FEAT. PROF. WADIE SAID:

The Department of Justice charged Dylann Roof, the white 21-year-old man who allegedly gunned down nine black churchgoers in Charleston, South Carolina on June 17, with murder, attempted murder and use of a firearm, all in the commission of a hate crime. Attorney General Loretta Lynch announced the charges on Wednesday afternoon.

But the DOJ did not charge Roof with domestic terrorism, or include terrorism in the indictment.
